TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM C. HUGHES, of Scio, in the county ofWashtenaw, and State of Michigan, have inventeda."new and improvedSelf-Raising Flour; and I do herehy declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same.

This invention or discovery relates to a new and useful methodofpreparing self-raising flour, and consists in a thorough and intimateincorporation of the fermenting principle with the flour when the grainis ground in a certain proportion, and at a low temperature, notexceeding blood-heat. The meal or flour of wheat, corn, and all otherkinds of grain may be prepared to render itself rising, that is to say,so impregnated with the ferment-ingprinciple that for making breadtherewith it will be only necessaryto add and mix a little warm water toproduce a dough that will rise well and make superior light bread. I I

My method of'preparing this self-raising flour is to make pure hop-yeastin the form of cakes, composed of meal or flour, and thoroughly dried,and in the proportion of one-half'pound of yeast, thus prepared andreduced'to a powder, to sixty pounds of clean grain, well mixed with theycast-powderygrind them together, care being taken to keep thetemperature of the mealin grinding below blood-heat. The floor will hepermeated in this manner with the fermenting principle, which willretain perfectly its full pdw'er to raise the dough, and make superiorlight bread whenever desired,- by'mixing it with warm water and workingthe dough in ,the usual manner before and after rising.

The ready self-raising flour will for this reason bo a. greatconvenience to housekeepers, asit will save the trouble of providing andaddingyeest to every batch of bread made.

.. Having thus described my invention, what I claim as new, and desireto secure by Letters Patent, is-

The preparation of self-raising flour in the manner herein described. l

The above specification of my invention signed by me, this 27th day ofAugust, 1867.
